Autogenerate tracing code for HTTP (and TLS) probes too #84
Description
At the moment, h2olog autogenerates tracing code only for QUIC-level probes.
It would be great if we could use that for HTTP- and TLS-level events too. To give an example, h3_packet_receive and h3_packet_forward are HTTP-level events that have been recently added to H2O. But neither of them are supported by h2olog.
